Final design and implementation is subject to municipal approval. 5.0 ALTERNATIVES 5.1 ALTERNATIVE DEVELOPMENT PROCESS The necd to reconstruct Lexington A venue has been recognized tor several years. Public meetings conducted at the time of reconstructing the Lexington AvenuelHighway 96 intersection in 1997 identified serious through lane capacity issues. Equally important, however, was the need to provide safe hrrning movements for driveway and side street access -- elimination of the center left hIm lane in order to allow two through lanes in each direction was not considered acceptable. The consensus was that additional road width was a prerequisite to support additional through lane capacity without loss of safe left turn provisions. An interim partial improvement was ordered in 2002 to take advantage of the 52-foot cmb-to-curb width. Thc roadway was re-striped to support two south bound through lanes, one center left turn and one north bound through lane. Additional public discussions/work sessions resumed in the fall of2003 through summer, 2004. The following lists dates and locations of public meetings: .

The baseline "no build" was summarily dismissed, as deficicneies in capacity and safety would remain uncorrected. Additional pressure was recognized in the fonn of Ii sing traffic volumes, fueled in part by new development and redevelopment (ie. Guidant Teclmologies, Inc.) north and south of the corridor. Two primary alternatives emerged as viable solutions to capacity and safety. Alternative Two (2) provides for a five (5) lane section -- two through lanes in each direction plus a continuous left hand hlrn lane. Right turns would also bc adeled at all side streets. Alternative Tlu'ee (3) also provides for two through lanes in each direction plus right turn lanes at side streets, but introduces raised median channelization instead of a continuous left hand turn lane. 5.2 CAPACITY OF ALTERNATIVE CROSS-SECTIONS The capacity of an urban arterial is usually determined by the capacity at signalized intersections, since these are the locations at which there are also large volumes of crossing lraffic and lhcrefore the through movement on the arterial is interrupted. The actual capacity at any specific intcrsection will depend on the geometry and traffic conditions at that intersection. Additional turn lai'1es may also increase the capacity at an intersection. The typical daily volumes that can be carried on different cross-sections at an :22. 2!)i)~- \v':_'nu'~' [';1('\:' 10
